Integrating AI with Open-Meteo API for Enhanced Weather Forecasting
detail.loadingPreview
This workflow creates an AI-powered weather assistant via a hosted web chat. It intelligently uses OpenAI and custom tools to first geolocate a city and then fetch its detailed weather forecast based on user queries, demonstrating advanced AI tool orchestration.
About This Workflow
This n8n workflow showcases a sophisticated integration of AI with external APIs to provide enhanced weather forecasting capabilities. Users interact through a hosted web chat, asking natural language questions about weather. Behind the scenes, a LangChain-powered AI agent, backed by OpenAI, dynamically calls two specialized tools: one for geolocating a given city and another for retrieving a multi-day weather forecast from the Open-Meteo API. This eliminates manual API calls, offering an intuitive, conversational interface for accurate and timely weather information, perfect for travel planning or daily decision-making.
Key Features
- AI-Powered Chat Interface: Interact with an intelligent weather assistant through a user-friendly hosted web chat.
- Dynamic Tool Orchestration: An OpenAI-backed AI agent intelligently determines and executes the correct sequence of API calls (geolocation then weather forecast) based on natural language input.
- Seamless Open-Meteo Integration: Automatically fetches precise geographic coordinates and comprehensive weather data from the Open-Meteo API.
- Conversational Memory: Maintains context across interactions for a more natural and fluid user experience.
- Customizable Tools: Demonstrates how to build and integrate specific tools (functions) for AI agents to interact with any external service.
How To Use
- Setup OpenAI Credentials: Ensure you have an active OpenAI API key configured within your n8n instance. This credential will be used by the "OpenAI Chat Model" node.
- Activate the Workflow: After setting up credentials, activate the entire workflow to enable its functionality.
- Configure the Chat Trigger: The "When chat message received" node creates a hosted web chat. Access the webhook URL provided in its settings (e.g.,
https://your-n8n-instance/webhook/4a4.../chat) to interact with your AI weather assistant. - Test the Assistant: Open the generated chat URL in your browser. Type a query like "Weather Forecast for the Next 7 Days in São Paulo" to see the AI agent in action, retrieving geolocation and weather data automatically.
- Review Tool Definitions: Explore the "A tool for inputting the city..." and "A tool to get the weather..." nodes to understand how API requests are defined and how placeholders for AI interaction are configured.
